Change of direction in organised political group produces unfriendliness (5)
I believe the answer is:
frost
'political group produces unfriendliness' is the definition.
'frost' can be an answer for 'unfriendliness' (I've seen this in another clue). I'm not certain of the 'political group produces' bit.
'change of direction in organised' is the wordplay.
'change' indicates anagramming the letters.
'direction' becomes 'r' (r is abbreviation for right).
'in organised' becomes 'st' (I am not sure about this - if you are sure you should believe this answer much more).
'of'+'r'='ofr'
'ofr' is an anagram of 'fro'.
'fro'+'st'='FROST'
Can you help me to learn more?
(Other definitions for frost that I've seen before include "Chilly feeling" , "Ice crystals forming a white deposit" , "Frozen dew" , "Hoar" , "RD Wingfield's detective" .)
